Pilot Reem Ahmad's flight plan has her leaving Dulles International Airport and flying a Boeing 727 due east at 450 mph. There is a 65 mph wind with the bearing 60 degrees.
a. Determine the compass heading that Reem should follow.
b. Determine the airplane's ground speed. (Assume the speed with no wind is 450 mph)

Wind+heading= 450East
so whatever the NS compononent of wind must be counteracted by heading.
See if you can take if from here. 
It's not making sense to me. Could you please explain further?
